+# expect-webdriverio Playgrounds
+
+Workspaces for testing expect-webdriverio with Jasmine, Jest, and Mocha.
+
+## Setup
+
+From the project root, run the following commands:
+```sh
+npm install
+npm run playgrounds:setup
+npm run playgrounds:checks:all
+```
+
+To run a single project individually (for example, Mocha):
+```sh
+cd playgrounds/mocha
+npm run checks:all
+```
+
+## Visual Snapshots
+
+Visual tests can occasionally fail if the website's layout or visuals change. 
+You can update the expected snapshots by running:
+```sh
+npm run playgrounds:snapshots:update
+```
